Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473656, here are decompositions:

73 + 31473583 = 31473656
127 + 31473529 = 31473656
199 + 31473457 = 31473656
373 + 31473283 = 31473656
439 + 31473217 = 31473656
547 + 31473109 = 31473656
619 + 31473037 = 31473656
673 + 31472983 = 31473656

Showing the first eight; more decompositions exist.
